Filed: 1994-09-12
Abstract: PURPOSE: To provide an optical transmission system capable of executing ultra- high-speed and large-capacity optical soliton transmission at a long distance by suppressing timing with simple means. CONSTITUTION: This optical transmission system is compensated of the pulse compression effect by a nonlinear optical effect applied on light pulses and the effect of pulse spreading by a dispersion effect by using transmission paths consisting of optical fibers 2 for transmission which transmit the light signals formed by adding digital information to return-to-zro light pulses and plural units of amplifier repeaters 3 for compensating the loss of these optical fibers 2. At least one of light band limiting elements 4 which are flat in group delay characteristics near the central frequency are arranged at every period Z equal to a soliton period Zsol in the transmission paths.  The optical transmission system is so constituted that the product aBsol <2> of the curvature (a) near the central frequency which is the products of the intensity transmission functions of these light band limiting elements 4 and the square of the spectrum half- amplitude full width Bsol of the transmitted light pulses is within a range from 2.1×10<-2> to 8.3×10<-2> .

Title: Reducing device for room interior carbon dioxide in structure
Inventor: ETORI TADAAKI
IPC: B01D53/04
Filed: 1988-09-28
Abstract: PURPOSE:To enable room interior carbon dioxide to be reasonably and economically reduced, and environment to be kept comfortable by providing an open air intake stream course and a bypass stream course, with discharge rate controlling means according to the output of a carbon dioxide sensor. CONSTITUTION:On an open air intake stream course 2, the inflow course 13 and outflow course 15 of a thermal sway adsorber(TSA) 6 are provided with control valves 8, 9 consisting of motor valves or motor dampers as discharge rate controlling means, and a bypass stream course 7 is provided with a similar control valve 10. Then, the inlet section of the open air intake stream course 2 is provided with a carbon dioxide sensor 11. Air in the room interior 1 of an exhaust passage 4 is discharged into open air, but most of it enters a feedback stream course 5 and is put together with the open air of the open air intake stream course 2 and is fed into the room interior 1. Besides, the open air taken in the open air intake stream course 2 is divided into the air passing the TSA 6 and the air passing no TSA 6 with the by pass stream course 7. So far as the distribution is concerned, as the carbon dioxide density of the open air gets higher with the output of the carbon dioxide sensor 11, the air quantity is passed more through the TSA 6. This adjustment is executed by adjusting the opening of the control valves 10 and/or 8 based on the output of the sensor 11.

Abstract: PURPOSE:To obtain a homogeneous artificial leather having elasticity, moisture permeability, external appearance, etc., close to those of natural leather, by utilizing hide powder having lubricity and a specific particle size in producing the artificial leather consisting of the hide powder and a thermoplastic resin compound. CONSTITUTION:30-70% hide powder obtained by pulverizing natural hide waste, e.g. cattle, horse, etc., in an absolute dry state is homogeneously blended with 30-70% thermoplastic resin compound, e.g. vinyl chloride, etc., and the resultant blend is hot-rolled by calender rolls to form a sheet 4. One surface thereof is then sanded to remove the resin skin layer (4a) on the surface to lines (C) and (C). Thereby the aimed suede artificial leather having the fuzzed surface is obtained. In this case, since hide powder having lubricity and 50-250 mesh particle size is utilized as the hide powder and the thermoplastic resin is bonded and connected in the outer peripheral part without entering the above- mentioned particles, the flexible artificial leather can be obtained without losing the elasticity.
